• Evaporation of water from the ocean

• Mouth of a river dumping freshwater into an ocean

• Glacier melting into an ocean

• Surface water freezing at the poles

Which are examples of decreasing salinity?

• Precipitation into the ocean

• Evaporation of water from the ocean

• Mouth of a river dumping freshwater into an ocean

What is the temperature, salinity, and density like at the surface zone of the ocean (top) as compared to the deep zone (bottom) of the ocean?

• colder temperature, more salinity, and more dense

• colder temperature, more salinity, and less dense

• warmer temperature, less salinity, and less dense

• Warmer temperature, less salinity, and more dense

How do transpiration and evaporation compare?

• During both processes, liquid water changes to water vapor.

• During both processes, water vapor changes to liquid water.

• During transpiration, liquid water changes to water vapor, and during evaporation, water vapor changes to liquid water.

• During transpiration, water vapor changes to liquid water, and during evaporation, liquid water changes to water vapor.
